Yeah, I think using a normal for loop is better. I just came up with the
question because I wanted to use a for-each-loop in a simple
exercise-scenario, because it's a bit faster to write...
Anyway, what I wanted to do is:
for (Value value : $eventSet) {
// raise hell
}
Thats where I get the type mismatch.
Thanks :)
